50.3 SAVI Typical Application
In actual application, SAVI function is usually applied in access layer switch to check the
validity of node source address on direct-link. There are four typical application scenes for
SAVI function: DHCP-Only, Slaac-Only, DHCP-Slaac and Static binding. In network
environment, users can select the corresponding scene according to the actual requirement; in
double stacks network, while SAVI function associates with IPv4 DHCP snooping to use, IPv4
and IPv6 source address authentication is implemented.
Typical network topology application for SAVI function:
Client_1
Client_2
Ethernet1/13 Ethernet1/12
Switch2 Switch1
Ethernet1/1 Ethernet1/2
Switch3
Client_1 and Client_2 means two different user’s PC installed IPv6 protocol, respectively
connect with port Ethernet1/12 of Switch1 and port Ethernet1/13 of Switch2, and enable the
source address check function of SAVI. Ethernet1/1 and Ethernet1/2 are uplink ports of
Switch1 and Switch2 respectively, enable DHCP trust and ND trust functions. Aggregation
Switch3 enables DHCPv6 server function and route advertisement function.
Configuration steps of SAVI DHCP-SLAAC scene:
